  1. Nordic research networks Peter Villemoes NORDUnet A/S NORDUnet 2000 Helsinki 28-30 September 2000

  2. NORDUnet mission • Common international service provider for the Nordic national networks for research, by connecting them to each other and to the rest of the world • Common Nordic platform for international research network collaboration • International service provider for research networks in the Estonia, Poland, Russia, and Ukraine • Network development in the Nordunet2 project

  3. NORDUnet organisation • Legal body is Danish limited company - NORDUnet A/S • Shareholders are the Nordic states or state institutions • DK - UNI-C • FI - Ministry of education • IS - University of Iceland • NO - UNINETT • SE - Högskoleverket • Board members are representatives of the national networks, mostly the national managers • Financed by the Nordic national networks

  12. The Nordic networks

  13. Nordic users and cost

  14. NSFnet was the world hub until 1996 vBNS did not take over after NSFnet and commercial nets did not focus on research needs The STARTAP in Chicago was then created in 1998 In 2000 also Abilene offers transit inside USA and USA is again a world hub for research networks NORDUnet connected to STARTAP and Abilene since 1999 and will use Abilene for transit from 2001 The world wide research net

  19. Traffic sharing with commercial networks Traffic with the commercial Internet is an important part of an institution’s Internet traffic NORDUnet and the national networks can reduce the cost of commercial traffic by no-cost-exchange peering Peering has not been possible for commercial traffic with the USA, but cost optimisation can be achieved by bulk purchase USA commercial traffic is now cheaper via general purpose commercial networks than over the traditional dedicated transatlantic links In the future it may be expected that dedicated international and intercontinental bandwidth (links) will be needed for research network traffic only (ex. TEN-155, Abilene, STARTAP)

  20. Future NORDUnet must continue to respond to the needs of the Nordic national networks Plan for next year Set up a Nordic 2.5G structure as the physical basis for the Nordic collaboration Create and connect to a 2.5G European backbone (Géant) Consolidate USA connections into possibly 2.5G, with assured bandwidth for the research traffic
